Connecting PROFIBUS (X30P)
Connection to the PROFIBUS system is made using a 9-pin D-sub connector according
to IEC 61158. The T-bus connection must be made using a connector with the
corresponding configuration. The following figure shows the PROFIBUS connector that
is connected to X30P of the DHF21B/41B option.
Connecting the
DHF21B/41B
controller to
PROFIBUS
The DHF21B/41B option is usually connected to the PROFIBUS system using a
shielded twisted-pair cable. Observe the maximum supported transmission rate when
selecting the bus connector.
The twisted-pair cable is connected to the PROFIBUS connector at pin 3 (RxD/TxD-P)
and pin 8 (RxD/TxD-N). Communication takes place using these two pins. The RS485
signals RxD/TxD-P and RxD/TxD-N must all be connected to the same contacts in all
PROFIBUS stations. Else, the bus components cannot communicate via the bus
medium.
